"The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2013:1284 advisory.

    Puppet allows provisioning, patching, and configuration of clients to be
    managed and automated.

    A flaw was found in the way Puppet handled YAML content during
    Representational State Transfer (REST) API calls. An attacker could
    construct a request containing a crafted YAML payload that would cause the
    Puppet master to execute arbitrary code. (CVE-2013-3567)

    It was found that resource_type requests could be used to cause the Puppet
    master to load and run Ruby files from anywhere on the file system. In
    non-default configurations, a local user on the Puppet master server could
    use this flaw to have arbitrary Ruby code executed with the privileges of
    the Puppet master. (CVE-2013-4761)

    It was found that Puppet Module Tool (that is, running puppet module
    commands from the command line) applied incorrect permissions to installed
    modules. If a malicious, local user had write access to the Puppet module
    directory, they could use this flaw to modify the modules and therefore
    execute arbitrary code with the privileges of the Puppet master.
    (CVE-2013-4956)

    Red Hat would like to thank Puppet Labs for reporting these issues.
    Upstream acknowledges Ben Murphy as the original reporter of CVE-2013-3567.

    These ruby193-puppet packages are used by Foreman, which provides
    facilities for rapidly deploying Red Hat OpenStack 3.0. In this use case,
    Puppet master is used and exposed to these issues. Note that Foreman is
    provided as a Technology Preview. For more information on the scope and
    nature of support for items marked as Technology Preview, refer to
    https://access.redhat.com/support/offerings/techpreview/

    Users of Red Hat OpenStack 3.0 are advised to upgrade to these updated
    packages, which correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
